that cd footage of a family roughed up by security guards at a popular New York City hotel and casino allegedly. They're suing Harrah's. Brian Ross has the story. ? Reporter: In a Jersey oceanfront resort of atlantic City, a place where everyone is welcome. Gamblers, hip stars and family. That's not what the Binz family found. It was miserable. It was absolutely miserable. Reporter: University of Pennsylvania student and class Cal guitarist SHAWN oaks fared no better. He says his disagreement with the hotel security guard got him pumped, kicked and stomped on according to his lawsuit. Not what you expect when you come to Atlantic City. Not what I expected. Reporter: Even worse for former college basketball player rob Koenig after a nightclub. I was laying in a pool of my own blood. Reporter: All of this took place in one casino in atlantic City, Harrah's, part of the giant Caesar's entertainment now being sued by the unhappy customers. In the case of the Binz family. Security moved in after Binz became upset when told he was being evicted because the hotel computer mistakenly did not list him as a guest. Even though they had been staying there for two days. Watch what very few would call good hospitality. They grabbed him and just slammed him to the floor and all I could say was, get off of him. He's got a pacemaker. Reporter: Then his mother and daughter headed for the elevators to the room and security swooped in to stop them. First the teen daughter is wrestled to the ground and handcuffed and then mom brought down and dragged off by a man in shorts who her lawyer says is the casino's head of security. It ended up with early termination of what was supposed to be a very nice family trip. Reporter: All this comes as Atlantic City is struggling to improve its image and appeal to tourists and the mayor was upset by what he saw when we showed him some of the videos. Beating can't be tolerated. It's unacceptable. Violence can't be tolerated. Reporter: Harrah's employees claim the Binz and the other two were the aggressors. Mr. Brian Ross from ABC news. This director of security would not answer any of our questions. Sir, we're not allowed to comment. Reporter: You think this is appropriate that you go over the line? Later in a written statement the casino said its security personnel are trained to use the least amount of force required while taking necessary steps to protect guests, employees and themselves. But there was no comment on any of the cases involving the dramatic videos. Brian Ross, ABC news, atlantic City.
